Underwriters Laboratories Installation Notice

Per The Underwriters Laboratories standard 1459, 2nd edition, be aware of the following
precautions when installing telephone equipment that is to be directly connected to the telephone
company network:
• Never install telephone wiring during a lightning storm,
• Never install telephone jacks in wet locations unless the jack is specifically designed for
wet locations,

disconnected at the network interface,

Hybrid Installation

Whenever a programmer assigns lines to line groups, the digital telephone system automatically
assumes the hybrid mode. Your local telephone company may charge a higher monthly fee for
operation of a hybrid system; therefore, the FCC requires that you report the equipment-type
category designation number (KF for key system, MF for hybrid system) to the telephone
company at the time of installation.
